Critical Seeds


Critical is a “massive” production plant carefully bred to produce some monster yields, clocking in at 600 grams per M2 and up. It was developed to mirror the growing capability of Big Bud and it delivers on that promise. Besides its ability to flourish in practically all conditions, it also produces buds with a well-balanced profile of effects.

Here at MSNL, we worked with more than 10 different Critical Mass phenotypes and five Big Bud phenos to arrive at the best version of a Critical strain we could devise. Not only can you expect high yields when growing this strain, but you can also expect moderate THC levels of 15 to 18%.

Strain Effects

This Critical strain provides the optimal blend of cerebral and body effects into one strain. When smoking it, there’s a nice active head high that combines with a warming and soothing body buzz. It’s a strong stone, but not one that’s overpowering. Essentially, you’re getting equal amounts of calming, couch-lock effects with a productive and creative heady stone.

Growing info

This easy to grow high yielder makes for an awesome commercial plant. When we say high yields, we’re talking upwards of 600 grams per M2 or more. It’s a beautiful sight to see, and it doesn’t take long to get there with flowering times of only 8 to 10 weeks putting the outdoor harvest around late September. When grown indoors, you may need to guide the plant a bit, but overall it’s a great plant for beginner growers and is super simple for master commercial growers to pull off.

Appearance and Aroma

As a massive production plant, you’ll see massive size buds. They are dense and chunky with a beautiful green color. Often, they’re covered in frosty crystals and release a sweet fruity smell with citrus and skunk undertones.

MSNL Editors Verdict

As a labour of love strain, we are happy with the volume of cannabis that it’s capable of producing. It was our intention to breed a big-time producer, and that’s exactly what Critical does. Also, it grows well indoors and out, is meant for any skill level of grower, and has wonderful bodily and cerebral effects packed into one strain.

YIELD >600 g/m2
Tasting Notes

When taking your first inhale of Critical, the taste is sweet with hints of lemon. Then as you exhale, the taste left on your lips and your taste buds is slightly hashy with notes of cinnamon. Like the effects, the flavours are also uplifting yet mellowing for wonderful flavours that pair nicely together.

  • "Great Yield & Good Smoke"

    Review by

    This is an update to my last post. Although I only had a 40% germination rate and 2 of the four plants were males--the two females were great. They were over 8 feet tall with very large yields and the buds had about 18% THC (I tested it). Great plants but the seeds I bought were only about 40% viable.

  • "ALL popped"

  • ""Huge yield""

    Review by

    I received some of these as free seeds, and tried them grown outdoors. Given room these grow huge, decent yields of a good smoke. I found them useful for pain relief and sleeping. Thanks Msnl !

  • "Very poor germination rate"

    Review by

    I ordered 10 Critical seeds and also got 5 free White Widow seeds. All 5 of the free seeds germinated. Only 4 of the 10 Critical seeds germinated. They were all germinated in the same conditions. A 40% germination rate is very poor. I will see how the plants grow and produce, but I am NOT happy so far.

  • "Critically Acclaimed"

    Review by

    I was really impressed by the delivery of these Critical seeds. Very cool MSNL. Many thanks for the freebie seeds too! I'm going to grow at least one male plant for the pollen in order to cross it with something interesting, just for the fun of it! I ned not bother though, Critical is a high-yield plant (hence the name Critical Mass), which is easy to grow and take cuttings from. I look forward to growing these beans!

  • "Harvest in a few days!"

    Review by

    Got this strain as a freebie in an order I got a few months ago. Only germinated one seed hoping it would be a female and luckily it was. She is very easy to grow and take care of. Almost everything in the description is exactly how this plant turned out. Even the picture looks damn close to what the colas on my plant looks like. Wish I did some more training on her cuz she did get tall. A lot taller than I expected cuz it really stretched during the first few weeks of flower. She has a very strong sweet aroma that blasts my face every time I open the tent. Such a beautiful plant! The buds are big, chunky, and covered in frost and has some really nice colors. And during the last couple weeks up to harvest she brings out some fantastic colors in the leaves as she fades and uses up nutrients stored in her leaves. Cant wait to harvest and eventually try after a nice curing process. Definitely getting a substantial yield from her. Did take longer to finish than what the description says but well worth the effort and wait. Highly recommend.

  • "My first time growing"

    Review by

    I'm new to growing weed but have been growing fruit trees for 15 years. Got some Critical seeds and Thai stick.
    Took 3 critical seeds and used the paper towel method was surprise how fast they sprouted. (2 of the 3.) Had such a long root that I needed to plant them earlier then planed
    Happy with the results so far.
    Delivery was as expected.
    Happy with my purchase.
    Thank you

  • "Great yields"

    Review by

    Although not the strongest on the market this strain really does have a lot going for it.. reasonable smoke with massive yields can take a fair bit of abuse and neglect if you want to make $$$ this stuff will not disappoint no complaints here great value

  • "Four Stars"

    Review by

    It is in my opinion that although this strain is surprisingly potent and heavy in its aroma, that somehow and somewhere within the genetics of this strain a portion of its quality was sacrificed in its interest of quantity (the high yield of the subject).
    It is important to remember that this Type was designed as a commercial yielded, and it is in fact that, an impressively high yielded.
    It is in my opinion that Critical falls a bit short to qualify as being medicinally beneficial.

  • "Not enough"

    Review by

    As a toker, and not a grower, I'm not interested in how big the buds will get, or how many there will be. I just want a great stone! For me, this wasn't it.

  • "Great yielder"

    Review by

    One of the best yielders I have done so far very skunky smell and just a great plant to grow! It clones very easy better than most all around great strain

  • "Holy crap the yields!"

    Review by

    I grew this outdoors and so didn't expect to get the most buds ever. BUT I did! They're just massive, you have to see it to believe it. Definitely worth the time and effort spent by MSNL, as I think they've created their greatest bud yet.

  • "Superb genetics and easy to clone!"

    Review by

    This plant responds well to supercropping. Pulled the males out as soon as they were identified. Clones were successful. Nearing peak harvest the aroma is a citrusy scent.
